North of Gasconade Street, there is a long apartment building, which is amazingly stuffed into what is really the space for a large house. It shows how much demand there once was for high density housing in the early decades of the Twentieth Century. I would also note that many large apartment buildings such as these are actually just four-families or six-families built right next to each other.
This block gets concerning, however, as there is much abandonment heading north past the alleyway and the large apartment building.
This last house faces Osage Street, and its City listing of 1890 as date of construction is clearly not correct. It probably reflects an addition. I would suspect this is an incredibly old house, dating back to when this was far out in the countryside.
